SPECIFICATION forming part of Letters Patent No. 351,883, dated November 2,1886.

Application filed September 2, 1886. Serial No. 212,513. (No model.)

To all whom it may concern:

Be it known that I, EZRA S.,PACKARD, a citizen of the United States, residing at Harnmonton, in the county of Atlantic and State of New Jersey, have invented certain new and useful Improvements in Broeders; and I do declare the `following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specitication.

This invention relates to brooders for raisp ing chickens in large numbers without'the aid `formed, which are separated by partitions b.

of the mother hen. Y

The improvement consists in the novel features presently to be described and claimed,an'd shown in the annexed drawings, in whicht Y Fignrel is a side view of a brooder embodying my improvements, parts being broken away. Fig. 2 is a section of the same on the line ma: of Fig. 1. Fig. 3 is a detail view show` ing the means for closing the air-inlets. Fig. 4L is a plan view of one of the elevated platforms, and Fig. 5 isa perspective view of the artificial mother.

A represents the'iloor of the brooder, beneath which a series of compartments, B, vare Directly above these compartments are formed brooders C, each of which consists of an elevated platform, Dhaving sides d, to which the wire-netting d is secured. An air-cham' ber is formed between the floor and elevated platform, for the purpose lof preventing the brooders from' becoming overheated to the great detriment of the health of the chickens. The height or distance of the platform from the door can be regulated by setscrews D', located at each` corner thereof and bearing upon the floor. Air is admitted to saidv space by inlets D2, formed in the side of pieces D,which embrace the sides of the door.

Tubes E, secured at their upper ends to the elevated platform, extend through openings in the floor, and afford communication between the compartments and the brooders. They pass loosely through the iioors, so as not to interfere with the raising and lowering of said platforms, for the purpose already set forth.

The artificial mother is placed directly over the protruding ends of the tubes E, and. consists of a top, F, adj ustably supported on pins Witnesses:

f, passed through each corner. The inner side of the top is cushioned in any desired manner, and curtains f', depending from the edges, serve to retain a sufficient amount of heat for the brooding of the chickens under said mother.

Aseries of heating-pipes, G, extends through the compartments for the purpose ofv Warming the freshair supplied thereto through the inlets or air-passages h. They run in any desired direction, either parallel or return-bends, but preferably in the manner shown, in which G extends the entire length of the brooderhouse, and has branches G2 projecting therefrom at each end of the compartment, the outer ends of which are joined by a series of short pipes, G3, united in a zigzag shape, as shown. Near each end the branches G2 are provided with valves g', for regulating circulation ofthe heating medium Vthrough said branches. valves g2, arranged between the ends of the branches G", serve to cutoff the heating medium from or direct it to any particular brooder.

The

In a compartment at one end of the series y of broeders is located the heating apparatus, comprising the boiler -H and tank l. At the other end of the series connection is made with return-pipe J by a series of short pipes, j.

The inner ends of the-air-passages It `are closed by valves K, which are pivoted between their ends, one end of which is adapted t0 close the opening, while the other end is bent at right angles, forming a handle, k, which eX- tends upward through an opening in the floor,

within easy reach for opening and closing said air-passages, as desired.

It will be noticed that the floor has a series of openings formed therein, corresponding t0 the position of the several valves g g2.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

The combination of a continuous series of broedersY having. compartments formed beneath them, the heating-pipes located in said compartments, the air-passages leading therein, the Valves for controlling the passages, the elevated platform, and means for raisingand `lowering it, substantiallyas and for the purpose described. l

In testimony whereof I aiiix my signature in presence of two witnesses.
